      Handle `NamespacePlacementChanged` control events in degraded mode, and query the `DataToShardsAllocationQueryService` for the cluster time embedded in the event.
      If the `DataToShardsAllocationQueryService` cannot provide information for the specified timestamp, the change stream will be downgraded to v1 mode.
